| Learning Objectives | Lines and planes are presented from a vector point of view alongside the decod.es implementation of these classes. In the workshop, we will practice manipulating properties of these simple geometric objects in addition to more list iteration to generate patterns such as fractals and guilloche lines. |

Workshop
The workshop file can be accessed on the Class Dropbox under Workshops/ week4 .ghx
This includes basic usage for some useful classes that have not gotten any treatment in class yet, such as PGon (including stock polygons like Rectangle, Doughnut) in addition to Xform (class of transformations).
Relevant Examples
All of these can be found in the Examples folder:
- Fractals
- Guilloche
- Simple Inflation
Assignment
There are two parts to this assignment, both of which are building up to your midterm project due 10.27 which will be explained in detail next class.
A: In class you developed a generative pattern (a fractal) by iteratively applying a simple rule that replaces a line segment with a collection of line segments. The pattern that emerges can be surprisingly complex after just a few iterative steps. This fundamental iterative process can involve any geometric object whereby a generative rule specifies drawing or replacing the original object by a collection of like objects. For instance, in Examples/Simple Inflation, the generative rule is to draw a polygon whose vertices are at the same fraction of a distance along each segment of the initial polygon. In addition to playing with the rule that you developed in class, try your hand at a generative pattern based on another object (such as a circle polygon, rectangle, polyline on a plane). You can stick with patterns in 2d, but you may also want to try out some generative rules that result in 3d patterns. For some inspiration, take a look at images that come up under keywords of “L-systems”, “Iterated Function Systems”.
Please have the following in your Dropbox/[your name]/week4 before class:
- One image based on the rule that you developed in class. Some of you already had promising results on your screens at the end of class, but take some time to compose this image on the extents of the page (no screenshots anymore please!)
- An image sequence of a generative pattern based on another object, showing the progression from its initial step to your chosen result.
- One .ghx file cleaned up and labeled so I know where to look
B: With your assigned midterm partner (if you don't have one, let me know) bring in 3 examples of buildings that have geometric differentiation at the facade in response to the sun. This may be in the form of an ocular shading device (fins, overhang, brise-soleil) of varying size and spacing or windows set at varying depth in the wall. Print out your examples (one page per) and be prepared to discuss these in class.
